2. The Interface

The computer interface refers to a USB computer interface. This
type of interface is found on IBM-compatible PCs or laptops.

To connect the IB-COM (socket 5) with the USB interface use the
Uhlenbrock USB cable Part No. 61070. That is a USB cable with
connector types A and B plug, like you also use for connecting a
USB printer.

The computer interface is set to a data trans mission rate of 115200
Baud.

The USB LocoNet interface of the IB-COM can be used with the
Windows Operating systems 2000, XP and Vista (32 bits, without
active users access control (UAC)). Support for older Windows
systems like 95 or 98 is not provided.

For layout control all PC-control programs that support LocoNet
protocol can be used.

2.1 Interface Characteristics

PC and LocoNet are electrically isolated. Baud rates of 19200,
38400, 57600 or 115200 Baud can be selected.

Two operating modes are available:

1. all bytes are passed directly to the LocoNet (only 19200 Baud)

2. only valid LocoNet Messages are transferred from the PC to
LocoNet; the interface controls the data traffic on LocoNet; all
Bytes from LocoNet are passed directly to the PC (factory
setting).

2.2 Preparation for installating the driver

Before you connect the IB-COM to the PC, the driver software for
the interface must to be installed otherwise your PC may
malfunction.

To install the driver insert the CD into your CD-ROM drive. After
short time the program will start and guide you through the
installation process for the software.

If the installation program does not automatically start, open the
CD-ROM with File Manager or Explorer and start with a double click
on “CDRUN.EXE”.

Precise instructions for the installation are found in the following
sections for operating systems, Windows 2000, Wind ows Vista and
Windows XP.

With successful installation the PC has a new COM Port with the
designation “Uhlenbrock into USB-LocoNet-Interface”.

Now the interface can be addressed by software via the COM Port.
Connect the IB-COM USB port (socket 5) to the USB interface of

the computer.
For the connection use the Uhlenbrock USB cable Part No. 61070.

It is a USB cable with an A and B type of plug, such as is al so used
for connecting a USB printer to the computer.

2.7 Interface Configuration

Since the interface on the IB-COM technically is the same as the
LocoNet interface 63120 it is setup in the same way by LocoNet
programming (see chapter 4.3).

As part number you use 63 120; the module address is 1.

2.8 Communication PC – LocoNet (only for Experts)

Communication between PC and LocoNet must be according to the
following protocol:

Send message over USB and wait until the sent message is
received again, before sending a ne w message. If other messages
are received during the waiting period process them.

LACK (Long Acknowledge Message) treatment: If a LACK can
follow a message (see LocoNet documentation for the messages
that can be follow by a LACK), a flag must be set by the COM Port
after a send and receipt operation. If this flag is set and the next
received message is a LACK message, then this must be
processed because it is a reply to the sent Message. If the next
message received is not a LACK the set flag is reset. This way
ensures that a LACK is not assigned to a wrong Message.

Process Received Messages.
The echoed messages sent by PC do not have to be processed

upon receipt, since after transmission to LocoNet they appear in the
receive buffer and are processed by the receive routine.

Sending Messages without control of the return echo can lead to
errors in communication between PC and LocoNet. By this method
using a Baud rate of 115200 Baud will decrease the speed of
communication.

2.9 LocoNet Direct Mode

If the LocoNet direct mode is selected (LNCV 4 = 1), then each byte
is sent directly to the LocoNet without any control by the interface.
This mode should only be used with the Baud rate of 19200.

The settings for the interface remain even if the IB-COM
configuration is put back to factory default.

3. The IB-COM connectors

This chapter describes the connectors of the IB-COM and shows
what must be taken into account when different devices are to be
connected to the IB-COM.

3.1 Definition of the IB-COM connectors

The image below is the rear view of the IB-COM with all its
connectors.

1. 6-way header: Transformer, normal track, programming track

2. RJ12 socket: LocoNet T (Throttle)

3. RJ12 socket: LocoNet B (Booster)

4. 3-way header: DCC-Booster

5. USB-Socket: USB Computer interface

3.2 Preparation of the clamp plugs

Two clamp plugs are supplied with the booster to
connect the transformer, the normal track and the
programming track. Use a work bench or similar
surface to connect the cables to the clamps.

The cables which are to be attached are
manufactured from braid or wire with a cross section of at least

0.5mm², with at least 6 mm (approx.) stripped at the end. Carefull y

twisted and after that possibly tinned.

The 3-way clamping plug is opened by a
light pressure of the plug’s clamping
device with a narrow screwdriver (2
mm) through the top opening. A cable
with stripped end is inserted into the
clamping plug from the front. By
releasing the screwdriver the cable is
fixed in position and a safe contact is

made.
The 6 pin plug for connecting the transforme r,

track and reversing loop is a screw terminal
plug with which the cables are fixed by
tightening the screws.

3.3 Connecting transformer, track and programming track

The 6-pins plug 1 is used to connect the transformer, the track and
the programming track.

1 Programming track
2 Programming track
3 Digital voltage to the track
4 Digital ground to the track
5 Ground 16 V AC from Transformer
6 16 V AC from Transformer

The transformer

In order to obtain a trouble free operation of the IB-COM use a
transformer of min. 52 VA output power. The maximum ou tput AC
RMS voltage from the transformer should not exceed 18V.

The transformer must be connected to clamps 5 and 6 (brown and
yellow, respectively).

Ensure that the wires from the transformer have not been swapped
with those from the track, and that short-circuits did not occur
among the various wires of the connector. A short-circuit between
the transformer and the track could destroy the output stage of the
IB-COM.

The track

For 2-rails tracks, the track must be connected
to terminals 3 and 4 of 6-way plug.

For 3-rails tracks (Märklin) the track centre rail
is connected to terminal 3 (red Märklin cable)
and the track ground to terminal 4 (brown
Märklin cable) .

The programming track

The programming track is a special track for programming and
reading out the configuration variables of loco decoders.

Both rails of the track must be isolated from the normal tr ack! With
Märklin tracks you isolate rails and centre rail.

During programming the isolation gaps must not be brid ged (wagon
locomotive bogies).

The track is connected to terminals 1 (brown) and 2 (red) of the
screw terminal plug for socket 1.

The Programming track can only be used for programming and
reading of decoders. It cannot be used for running trains.

If the programming track is also to be used for traffic it must be
connected to the track via a change over switch (e.g. our Switching
decoder SD1, Part No. 67500).

If the connections to the programming track are exchang ed the IB­COM switches off as soon as a vehicle drives over the isolation to
the programming track.

3.4 Connecting a DCC booster

DCC Booster can be connected to socket 4. They can output
Motorola and DCC data formats.

Lenz Booster

The signal lines C and D and the short signal line E must be
connected to the 3 pole clamp plug as shown in the picture.

1 C = Signal +
2 D = Signal ­3 E = Short-circuit signal line

Märklin- and Arnold Digital= Booster

Märklin Digital = Boosters (6016) and Arnold Digital = Boosters
(86015) can be connected to connector 2 with help of Uhlenbrock
adapter 61 030.

Other DCC boosters

Usually, DCC boosters have only two wires. These wires should be
connected to terminals 1 and 2 of connector 4.

Because of the connection of “E” the boosters are not able to
transmit a short-circuit signal to the IB-COM, but they are usually
protected by their own short circuit protection.

3.5 Connecting a LocoNet Booster

LocoNet must be connected to connector 3 (RJ12) for LocoNet B on
the rear of the IB-COM.

These boosters are not able to transmit a short-circuit signal to the
IB-COM but they are usually protected by their own short circuit
protection.

3.6 Connecting LocoNet

All presently known LocoNet devices can be connected to the IB­COM.

The LocoNet Booster must be connected to the LocoNet connector
B (Socket 3). LocoNet control panels. LocoNet throttles and other
LocoNet control devices should be connected to the LocoNet
connector T (Socket 2) which delivers no digital track signal.

3.7 Connecting Computer Interface

Before you connect the IB-COM to the PC the driver software for
the interface must be installed (see chapter 2), otherwise your PC
may malfunction.

The computer interface is a USB Computer socket. This interface is
found on IBM-compatible PCs or laptops.

Use Uhlenbrock USB cable Part No. 61 070 to connect the IB-COM
(socket 5) with the USB interface of the computer. That is a USB
cable with A and B type plugs as it is also used for connecting a
computer with a USB printer.

The computer interface is set to a data transmission rate of 115200
Baud.

4. The Utility Software

Before the first use of the device you must install the USB driver
(see chapters 2) and the program IB_Util.exe.

The program “IB_Util.exe” is to be found on the equipment encl osed
utility CD. It makes the connection to the interface of the IB-COM
and puts the following functionality at your disposal:

a Workspace with driving desk, keyboard and feedback monitor,
which you can use for simple driving and switching tasks,

the Settings menu, with the data format, special options and dev ice
Reset submenus,

the Tools menu, for easy programming of DCC decoders and
LocoNet modules.

4.4 Settings – Basic Settings “Optional Settings”

If desired other settings can be changed in the Basic Settings
menu.

On-time for solenoids

When a solenoid is switched, t wo instructions are required, one to
switch the solenoid on, and the other in ord er to switch the sole noid
off again. If these Instructions are given to the center directly after
one another without a pause

the center will switch the solenoid on for
the adjustable “minimum switch-on time”. If however only a switch on
instruction is sent and no switch off instruction, the center independently
switches the solenoid off after the “maximum Switch-on time”, in order
to prevent an overload of the solenoid.

Number of Packets sent per instruction

If the DCC data format for the control of solenoids is us ed then the
number of packets sent by the center per solenoid instruction can
be configured here. Solenoid decoders that do not immediately
react can possibly be induced to operate by an increase of this
setting.

“STOP” – status

If this option is ticked the IB-COM powers up in the “STOP” state
with track power switched off.

4.5 Settings – “Locomotive Data Format Individual”

If you want to control individual locomotive decoders with a data
format other than the general locomotive data format, then you can
set up their own data format individually for each locomotive
address.

Click the “Read” button to read the current speed step curve.

The individual points of the curve can now be changed with the
mouse. When the desired curve is adjusted the changes can be
programmed into the decoder clicking the “Program” button. The
values of the curve are transferred to the CV list and saved along
with the other CVs.

4.10 Tools – “LocoNet Module Programming”

The “IB_Util.exe” program has a men u option for the programming
of Uhlenbrock LocoNet modules such as feedback modules or
Switch-Control.

The modules are programmed using LocoNet Configurations
Variables (LNCVs). These LNCVs determine the configu ration and
functionality of the modules and can have different meanings for
different modules.

The description of the individual LNCVs, as well as the connecti on
of the module is found in the respective operating instructions.

4.10.1 Programming the Module Address

In a model railway layout with several modules of the same type
they all require a unique module address for programm ing, so that
the center knows which module is meant.

Each new module has a particular ex-factor y default address from
the basic setup of the processor. These can be determined from the
relevant manual.

Procedure:

• Connect the module to the LocoNet

• Start “IB_Util.exe”

5. Software Update

The IB-COM system software can be updated to a newer version,
by downloading the new software from the computers, through the
serial interfaces.

There is no need to open up the IB-COM!

Hardware requirement

• You need to power the IB-COM with a transformer.

• You will also need a serial cable to connect the IB-COM to a

Personal Computer.

• Disconnect the IB-COM from the layout LocoNet.
Software requirement

Contact your local retailer to obtain the u pdate of the new driver, or
download it from our Internet site www.uhlenbrock.de.

Procedure

• Switch the IB-COM off for 5 seconds and then on again

• Start the program "IBCOMWinupdate.exe" and follow the

instructions on the screen.

Checking the software version

Under the “Settings - Serial and Version Number” menu the
“IB_Util.exe” program displays the new version number of

the

system software.

• Start “IB_Util.exe”

List of Special options

Special Option No. 25

In factory setting the IB-COM only sends a data f ormat if a decoder with the appropriate
format is addressed and is still in the refresh c ycle. Alternatively the IB-COM can be setup
so that this data format is constantly being output even if no address with this data form at
was called before.

For example the malfunctioning of some Motorola decoders can be prevented this way
where they automatically switch into the analogue mode th e instant they stop receivin g the
Motorola signal.

The input value is calculated by the follo wing table. The values of the desired options are
added.

Option Value

DCC signal only if required
permanent DCC signal

0
1

Motorola signal only if required
permanent Motorola signal

0
2

Example

If the Motorola signal is to be sent permanently and the DCC signal only if required the
input is calculated as follows:

DCC signal only if required value = 0
Permanent Motorola signal value = 2

The calculated sum (here 2) is entered as value for this special option.
Factory setting is 0.

Special Option No. 97

Determines the state of the IB-COM after it is switched on.
0 = [stop] key is activated. The driving power is switched off.
1 = [go] key is activated. The driving power is switched on.
Factory setting is 1.

Special Option No. 907

This sets the digital signal which the IB-COM transmits, if no locomotive is in a refresh
cycle, e.g. after switching on the layout before the first locomotive is called.

1 = Motorola
4 = DCC (factory setting)

Module address table for feedback channels

The IB-COM displays the individual feedback channels in blocks of 16. This corresponds
to the module addresses of s88-Modules.

After switching the IB-COM on the first block, the channels 1-16 are always dis played. If
other channels are to be displa yed, the appropriate modul e address must be entered from
s88-Mode after manipulation of the m key.

Converting bits to bytes

Some DCC decoders do not accept the “bit-wise” programming mode. When progr amming
a single bit of a configuration variable it coul d be necessar y to convert the 8 bits of a CV to
a complete byte.

Coding table for solenoid decoder

The address of decoders conforming to the Motorola format (from the companies Märkl in,
Viessmann and Modeltreno) is defined using 8 micro switches. Since every decoder
controls 4 solenoid devices, the decoder address is different from the solenoid device
address.

The following table shows the position of the 8 micro switches of these decoders. The
correlation with solenoid device addresses and Märklin Keyboard is also included.

Tips and Tricks

Some Märklin locomotives can’t be controlled

Older Märklin decoders (6080 and Delta decoders) can on ly be controlled with the IB-COM
if the red wire from the centre pick up is connected to the rail.

Old and new Märklin function decoders

The Panorama car and the Märklin Digital remote control rotary crane (7051+7652), are
controlled with the old Motorola protocol, using f1-f4 functio ns. They are not able to operate
with the new Märklin-Motorola protocol.

New Märklin locomotives (with smoke, sound effects, etc), new Märklin decoders (60901,
etc.) and Uhlenbrock decoders (755, 756, 760 in operatin g mode 1-3) operate only in the
new protocol, and ignore the f1-f4 function signals of the old protocol.

Problems controlling the lights in DCC decoders

If the locomotive lights no longer respond to the [function] key, it’s most likely that the
decoder is configured for 28 operating levels while the IB-COM expect 1 4/27 speed levels
for that locomotive address. To solve this situation, change (in the IB-COM) the
configuration of the relevant decoder address to 28 operating lev els.

Remember that NMRA standards impose the following specifications for CV #29:

14 operating levels t CV#29 Bit 1 = 0
28 operating levels t CV#29 Bit 1 = 1
128 operating levels t CV#29 Bit 1 = 1

Problems of DCC Decoders with other Data formats

Some DCC decoders have problems running cleanly if decoders using different data
formats are on the rails as well. These decoders falsely in terpret the Motorola data signal
as analog voltage and will "stutter" when driving or suddenly drive off with full speed.

With some decoders this behavior can be eliminated by switching off the automatic
recognition of the analog operation. How the decoder is configured to pure digital operation
can be found in the operating instructions for the appropriate decoder.

With some newer decoder types programming to pure digital op eration is done by setting
bit 2 of the configuration variable CV 29 to zero. Not e however that is not possible with all
DCC decoders.

With simple decoders there is no possibility of eliminatin g this problem.

Controlling the Märklin Digital turntable

The turntable can be retrofitted with a specific decoder (7687) compatible with the Motor ol a
protocol. The different functions respond to the solenoid devices addresses 225 to 240.

Attention!

The Märklin turntable decoder can only be put into programming mode within the first 5
seconds of switching on of the operating voltage. T he IB-COM needs approx. 13 seconds
to boot up. Subsequently the decoder will not accept any further instructions, if IB-COM
and turntable are switched on at the same time.

We recommend installing a switch in the yello w and red wires to the turntable decoder. The
switch remains open until the IB-COM has completed its b oot up. T hen it is closed an d the
programming process can begin, as in the operating instructions of the turntable described.

The addresses of the functions of the Märklin digital turntable

Controlling the Märklin Digital rotary crane

The address of the digital rotary crane must be configured for the old Motorola protocol.
The crane’s functions, like turning the cab and raising/lowering the boom, are controlled
with the : and ; keys and the speed knob. The working lights and the magnet are
switched on with the f key and switched off with the o key.

If, in multi-protocol operation, the crane should not respond correctly, try changing its
address.

Controlling the Roco crane wagon (Digital DCC)

The address of the Roco digital crane wagon (40110 or 46800) should be co nfigured for
DCC - 14 operating levels. The crane wagon uses one locomotive ad dress.

The different functions are operated with the [function], [off] and [f1] keys and turning the
corresponding knob.

Note: When programming the decoder an error message can be reported even if the
programming procedure was successful. The decoder address cannot be read on the
programming track.

Emergency stop button in the Lenz Booster output

If you connect the IB-COM ground (connector #1, pin #5) with the Lenz Booster short
circuit signaling line “E”, (connector #2, pin #3) with a momentary switch, the IB-COM will
shut off power to the track and to all connected Boosters.

You can have a number of “emergency stop” buttons,
connected in parallel, spread along your la yout.

Troubleshooting

Problem Cause Solution

The IB-COM does not turn
on.

The IB-COM does not have AC
input power.

Check the plug on the
transformer and the clamps in
socket 1 of the IB-COM.
Examine the connection
between IB-COM and
transformer and the mains
supply to the transformer.

The IB-COM can be switched
on, the green LED lights up,
but locomotives and turnouts
don’t operate.

The connection between track
and the IB-COM output is open
circuit.
If the track is attached to an
external auxiliary booster, then
the connection can also be
interrupted between the IB­COM and the booster or the
connection between the track
and the track output of the
boosters.

Check the connections for the
track on IB-COM socket 1
and the connection at the
track itself.
Check the cable connection
to the external booster.

The red LED flashes again
and again after only short
periods of operation and track
power can not be switched on

The IB-COM is constantly
overloaded by too many
running locomotives and lit up
trains. It overheats and
switches off.

Divide your layout into
several sections, isolated
from each other and feed
these with additional external
boosters.

The red LED blinks constantly The track has a short circuit.

The IB-COM overheated.
The track connected to an
external booster has a short
circuit.

Look for the item which is
causing the track short circuit
and wait until the IB-COM
cools down again.

Individual locomotives do not
run.

The locomotive decoders are
not addressed with the correct
data format.

Since decoders cannot give
feedback to the IB-COM, the
IB-COM cannot determine by
simply selecting the
locomotive address, which
data format is required to
control the decoder.
Check the data format
needed for each of the
locomotive decoders and set
it to the correct data format
(chapter 4.4).

A solenoid decoder does not
function.

The solenoid decoders use a
different data format from that
selected for output by the IB­COM as the general data
format for solenoid decoders.

Check the data format of the
“not working” solenoid
decoders and adjust it in the
“Basic settings” menu –
accessory setting – set the
correct data format for each
decoder used.
